We love NFC, therefore we decided to develop our NFC21 tools. Our app offers you an advanced yet easy to use toolset to explore NFC with your iPhone. Reading as well as writing of NFC-tags is supported and wrapped in an attractive user interface. NFC21 tools greets you with a history view, which contains all NFC-Tags you have read or written. Additional filters enable you to narrow down the list to ‘Read’, ‘Written’, ‘Drafts’ or ‘Favorites’ only. Tap on an entry for more details like the serial number (uid), memory size, write lock as well as the stored content. Based on the latter, an available action is offered like opening a link in Safari or the import of v-cards into the Contacts app. Creation of own NFC-tags starts with the selection of a type. We differentiate three different types. First, the standard-type creates NFC-tags which are readable by newer iPhones (iPhone XS, XR or newer) without an additional app. Second, extended types which offer more advanced scenarios like sharing of locations, contacts or WIFI-credentials. These types require a suitable app (like NFC21 Tools or NFC21 Reader) to read and process the stored content. Lastly, the expert type allows the definition of own datatypes, which require suitable / custom apps to use them. In summary, NFC21 Tools support the following tag-types: Standard (usable without an app with iPhone XS, XR or newer): • URL: Share a link to a website with an NFC-tag. Long / complicated addresses are a problem of the past. • Phone number: Share a number with NFC – always right and directly dialable. • E-Mail: Prepare a message for a recipient, ready to send with a tap. • SMS: Create a short message for a predefined number, an optional text and ready to send in an instant. • FaceTime: Start a FaceTime conversation with a scan. • Shortcut: Execute a shortcut from the apple shortcuts app with a simple scan. Advanced (with App): • Text: Hide a text within an NFC-tag, waiting to be read by a scanning fellow. • Address: Prepare a location for maps to ease getting direction – complicated street names are not a problem anymore. • Position: Locate an exact position (treasure)? Store longitude and longitude for use in the maps app. • Contact: Make your business card smart and let others scan your data like magic. • WiFi: Share credentials and ease login with a tag scan. Expert: • Data: Allows to define custom data types (MIME-Type). • Bluetooth: Share Bluetooth device IDs for easier coupling. Recommended NFC-Tag types: • NXP NTAG 203, 213, 215, 216 Support and NFC-Tags The NFC21 Tools app is developed by the NFC21 GmbH. Do not hesitate to send feedback and feature requests to our support. We recommend NFC-Tags based on the NXP NTAG-Series. In our online-shop we offer you a broad selection of NFC-products in various shapes and colors. Furthermore, we produce custom NFC-products based on your individual requirements. ## Key features - Read and write NFC tags - Manage tag history with filters - Create standard, extended, and expert tag types - Support for URL, Phone, Email, SMS, FaceTime, and Shortcuts - Advanced options for Text, Address, Position, Contact, and Wi-Fi - Define custom data types (MIME-Type) - Share Bluetooth device IDs ## Recent user reviews (10 of 53) All indexed reviews: https://appshunter.io/ios/app/nfc21-tools/id1496636288/reviews.md ### 1/5 — Can’t read all domains *2026-04-23, version 1.6* Won’t work with .xyz domains URL tags :/ ### 4/5 — Gut *2026-01-13, version 1.6* Gut soweit, erkennt aber NTAG215 als 216. Tippfehler in französischer Lokalisation. Keine einfache Möglichkeit Fehler in der App zu melden ### 4/5 — Please add dark icon *2025-11-06, version 1.6* Works perfect just needs a dark icon ### 1/5 — Tut nichts *2025-04-12, version 1.6* Iphone 14, ios 18.4: kann weder meinen Perso (klappt mit Ausweis.app) noch meine Bank- und Kreditkarten auslesen (keine Reaktion im Read-Mode) ### 5/5 — NFC21 *2025-04-09, version 1.6* Really good app and easy to use. If there was a pro version I would easily pay for it. ### 5/5 — Facile da usare *2025-03-27, version 1.6* Permette di leggere e scrivere Tag NFC anche economici. L’opzione scrittura propone tipi di dati predefiniti tra cui scegliere: dati, contatto, url, … Utile la funzione vocale che legge i dati ### 1/5 — Échec *2025-03-18, version 1.6* Ne fonctionne pas ### 2/5 — Presque parfait *2025-02-15, version 1.6* NFC21 Tools est probablement la meilleure app NFC mais il manque une fonctionnalité primordiale : pourvoir locker un tag NFC. Obligé de passer par une autre app pour ça, ce qui perd tout son intérêt… Une mise à jour est-elle prévue ? ### 4/5 — Schon eine sehr gute App, aber ... *2024-10-26, version 1.6* Die App gefällt mir insgesamt schon sehr gut, vor allem, weil sie auch mit VoiceOver gut zugänglich ist. VoiceOver liest zwar die Taste "Entwürfe" auch als "Eingang" vor, was mich zuerst etwas irritiert hat, aber nach Auswahl dieser Taste lautet die Seitenüberschrift korrekt "Entwürfe". Mir fehlt aber im Moment noch die Funktion zum setzen eines Passworts. Dafür muss ich aktuell noch auf die NFC Tools von Wakdev ausweichen. Wäre wirklich super, wenn dass noch nachgerüstet werden könnte. Man möchte ja manchmal vielleicht den Inhalt vor unbefugtem Überschreiben schützen, ohne dafür gleich den Tag endgültig zu sperren. Wenn die App die Passwort-Funktion bekommen hat, kann ich auch den 5. Stern noch rausrücken 😀 ### 2/5 — IOs 18 *2024-09-24, version 1.6* Leider nach IOs 18 nicht mehr Lesbar der Tag. ## Frequently asked questions about NFC21 Tools ### What does the NFC21 Tools app do?
